Application sind April t, 1907. seriale. 366,586.

To all 'whom it may, concern:

Be it known that I, JOHN LCK, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Wave-Motors, of which the following is a specification.

This invention relates to motors and particularly to that class of motors styled as wave motors because operated by the waves of some body of water.

The principal object of this invention is to so con struct and mount a motor of this class that waterhor other equally kmobile substance, shall be the prime mover in the motor, while the wave motion of water shall incite the prime mover to action.

To this end the invention consists in the 'structure and combination oi parts constituting the same sub.- stantially as herein described and claimed.

In the accompanying drawings, which -form a part` of this specification, Figures l and 2`represent, in side elevation and plan,l one embodiment of the invention, a portion of Fig. 1 being shown in vertical section, the plane of which section-is indicated by` the'linel 1-'-1, Fig. 2. Fig. 3 is aplan of another embodiment of the invention.` Fig. 4' illustrates in vertical section the. form of motor shewll'n Fig. 3, the'section being taken in the plane indicated by linea-l1. This figure also i shows the motor, mountedl upon a oat, in operation. Fig. 5 is a detail elevation oV the form oi power transmitting mechanism` used in the form oi motor represented inFigs. 3V and 4. v

The principal purpose of, this invention is toutiline water or some other equallymobile substance as the prime mover in developing power from, wave motion and it may be accomplished by employing an oblong yreceptacle loc'ated on, or parallel-to, the deck ofxa floating bodyl oi any sort, andcontaining a pistonor other movable partition, which shall slide with the coniined liquid towards one end or the other of the receptacle as the waves tilt the floating body. Obviously various forms of mechanisms may be devised and used in the accomplishment of` this purpose, and the motor, inwhatever form, may' be mounted upon any float in expanses of water where waves are usually present. It may be mountedupon the deck of avessel and power taken from it and utilized to propel the veeg l sel or for any otherI desired purpose, or it may be mount'- ed upon a float suitably anchored, and the power transv mitted from the float to the shore in any desirable manner. In Figs. l and 2, two boxes or tubes 6 and 7, rectan` gular or circular in cross section as desired, are represented located in alinement. In each there is a piston as 8, and these pistons are connected by a suitable piston rod 9, inthe middle of which between said boxes, is inserted a rectangular frame. The front half of the upper side of the frame is composed of a toothed rack 10, which meshes with a ratchet pinion 11 mounted on the shaft 12 and the rear half of the lower side oi the frame consists of a toothed rack 13, which meshes with a ratchet pinion 14, mounted at the side of pinion 11 upon shaft 12. These pinions may be connected to the shaft -by the Well known ball ratchet as shown in Fig.' l or by any other form of ratchet mechanism. The shaft 12 maybe supported in any suitable bearings, ordinary pillow blocks being indicated at 15. The power from this shaft may be taken off in any desirable manner as by sprocket gearing, the gear wheel of which upon said shaft isindicated at 16.

In the embodiment o'f themotor as seen in Figs. 3 and 4, one continuous box or tube is represented at 17 and in it is located a pistonrod as 18, upon which are pistons 19, two at each end., and in the middle of the piston rod is the rectangular frame 2O,l and within thi frame is a ratchet frame 21, against whose sides bear springs 22, whose tendency is to centralize the frame` 'for retaining the frame 'in place, has, for the sake of clearness, been omitted from Fig. 5. 4It may be secured to the frame 2O by any suitable means, as by screws passing through it into the holes indicated at 26.

For the sake of more fully disclosing the operation of this motor, a oat has been represented in Fig. 4 at 27, which loat may be anchored in any suitable way, as indicated by cables shown in dots at 28. This float may likewise be `considered as representing -a vessel. In either case the tube 17 would be extended lengthwise of the vessel or other floating body. In the tubel or box water is placed approximately filling half full the compartments between the ends o the box and the pistons and between the pistons themselves. Then as one end of the oat is elevated by the wave movement ofthe water on which it'- rides'; the water as indicated in said compartmentsI at 28, will rush towards the lower end oi the tube and carry with it the pistons 19 and likewise the frame 21. As the frame 21 passes from right to left its upper rack bar will engage the teeth of wheel 25, while the teeth of the'l'owerrack bar will ride over those of the wheel. Then las the` iloat tips in y-in the same direction as before, while the ratchet -pinion 14 moves'freely about the shaft.

Itors maybe located side by side if desired, substanshit used therefor as indicated in dotted lines at 29 fromwhich the power maybe taken. As stated above, f the power may be taken off the motor shaft in any mansenos? the opposite direction under the action oi the waves, the confined water will rush to the other end of the tube and, as the frame 21 moves from left to right, the teeth of the upper rack bar will ride over they teeth of the wheel, and the teeth on the lower side ofthe wheel will engage with the teeth of the lower rack bai",` whereby said wheel will be rotated in the same direction as before. Substantially this same -action takesy place in the form of motor shown in'Figs. 1 and 2,; wherein as water iiows to the left, the upper rack l0 will rotate its ratchet pinion 1'1 freely about the shaft 12, but the vrack 13 will cause its ratchet pinion 14 to grip the shaft 12 and rotate said shaft. Then as the water iiows tothe rigl1t,^the upper rack 10 will'cause its ratchet pinion 11 to grip the shaft'12 and rotate it Any-number of 'pistons may be employed and th tubes may be of any desired length. A number of Inotialiy as indicated in Figs. 2 and 3, and a common and uponthis shaft may be mounted a pulley as '30,

ner desired, as from a sprocket wheel 16, a band pulley 30 or a crank as indicated/m81..

It will be noted that the present invention combines with a'iioating body, a wave motor comprising means supported on the floating body and movable relatively thereto by the wave action and means connected with said first named means for transmitting power therefrom; and that in the present case the movement of 'the iirst named means e. the piston) is in alright or straight line and. that the motion is changed yto rotary motion through the described connectionm ',lvhel invention claimed-"f fy `1.
